CHLORAPREP ONE-STEP vs CHLORHEXIDINE GLUCONATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Chlorhexidine gluconate disrupts microbial cell membrane integrity and precipitates cytoplasmic contents, providing rapid bactericidal activity against a broad spectrum of gram-positive and gram-negative bacteria, as well as some fungi and viruses. Isopropyl alcohol denatures proteins and disrupts cell membranes, enhancing antimicrobial activity.
Cationic bisbiguanide that disrupts microbial cell membranes by binding to negatively charged cell wall components, increasing permeability and causing leakage of cytoplasmic contents; also inhibits bacterial enzymes and precipitates cytoplasmic constituents.
Apply chlorhexidine 2% and isopropyl alcohol 70% solution to the surgical site as a single preoperative skin preparation; no additional scrubbing or rubbing required.
Oral rinse: 15 mL of 0.12% solution swished in mouth for 30 seconds twice daily; topical: apply 2% cream or lotion to affected area 2-3 times daily.

Chlorhexidine has a terminal elimination half-life of approximately 1-2 hours in plasma after intravenous administration in animal studies; however, after topical application, systemic levels are undetectable, making half-life clinically irrelevant.
Terminal half-life approximately 12-24 hours; may be prolonged in hepatic impairment.
Chlorhexidine is primarily excreted unchanged in feces (>90%) after oral administration, with minimal renal excretion (<1%). After cutaneous application, negligible systemic absorption occurs, and any absorbed chlorhexidine is excreted renally as unchanged drug (<1% of dose).
Primarily renal (10-30% unchanged) and biliary/fecal (majority as metabolites).
